MYSQL LIKE HOW TO
MYSQL LIKE CODE

SELECT * FROM movies WHERE year_released NOT LIKE '200_' We would use the NOT logical operator together with the underscore wildcard to get our results. Suppose we want to get movies that were not released in the year 200x. The NOT logical operator can be used together with the wildcards to return rows that do not match the specified pattern. This is because the underscore wildcard matched the pattern 200 followed by any single character Notice that only movies that have 200 follows by any character in the field year released have been returned in our result set. The script below select all the movies that were released in the year “200x” SELECT * FROM movies WHERE year_released LIKE '200_' We would use the underscore wild card to achieve that. Let’s suppose that we want to search for all the movies that were released in the years 200x where x is exactly one character that could be any value. The underscore wildcard is used to match exactly one character.

MYSQL LIKE CODE

This is because our code matches all titles that start with the pattern “code” followed by any number of characters. Notice only one record has been returned from the database. JOIN Towns AS t ON u.Town LIKE CONCAT('%', t.Executing the above script in MySQL workbench against the myflixdb gives us the results shown below. #Do Inserts into temp table here with str going into the row LENGTH(SUBSTRING_INDEX(SearchTowns, ',', pos -1)) + 1), SET str=REPLACE(SUBSTRING(SUBSTRING_INDEX(SearchTowns, ',', pos), #pos - is the number of current word within search string

CREATE PROCEDURE GetUsersByTown(SearchTowns VARCHAR(200))ĬREATE TEMPORARY TABLE Towns(town VARCHAR(200)) For example, if SearchTowns contains 'Orangi' and 'Korangi' then users who are located in Korangi will be joined with both towns (because 'korangi' like '%orangi%'). All other rows which don't correspond this condition will be eliminated from the final resultset.Īlso I used DISTINCT to avoid rows duplication in case if userLocation.town corresponds to more than one row from Towns table. This is a stored procedure which splits inputed comma-separated string (SearchTowns) into separate rows, inserts these rows into temporary table (Towns) and then uses join between userLocation and Towns tables on required conditions (where userLocation.town is like %town% from Towns table).

MYSQL LIKE HOW TO

I have also looked at using REGEXP ValueA|ValueB but I don't know how to put the input parameter that is comma separated values in that REGEXP

I have tried to use find_in_set() but FIND_IN_SET does not accept wildcards like % and it doesn't use index? IN `SearchTowns` VARCHAR(200) - `ORANGI,FAISAL,NAZIMABAD`įROM userLocation where Town in (SearchTowns)

Sample Stored Procedure is CREATE PROCEDURE `GetUsersByTown`( I want to search all the towns against that query It could be just one, or two or three or all these mentioned above. I don't know how many towns would be there in the input. That is I want to use LIKE operator with IN from a stored procedure's parameter. Now I want to select all those above records against that input. Sample input of the towns parameter for the stored procedure would be like orangi,faisal,nazimabad. I am creating a stored procedure to search user's Towns.įrom the User Interface user will select multiple towns that will be sent to the stored procedure.
